5.2.1
The active power signal flow leads to the CF output pulse frequency, which is
proportional to the total active power being measured by the energy meter, the active
energy registers, which are in units of kWh and can also be phase gated using the
MODE1 register, and the active power output register (PHA_W).
Table 5-1 represents the registers being set during active power calibration.
